Two first guide grooves 4 are formed at the top of the workbench 1. Two moving blocks 5 are threaded on the surface of the bidirectional threaded rod 3. A first motor 6 is connected to one side of each moving block 5. The output end of the first motor 6 passes through the moving block 5 and is connected to a side cutting blade 7. A gantry frame 9 is connected to the top of the workbench 1. Second guide grooves 10 are formed on both sides of the gantry frame 9. A second guide groove 10 is formed at the top of the gantry frame 9. An electric actuator 11 is provided, the output end of which passes through the gantry frame 9 and is connected to a cutting blade holder 12. The cutting blade holder 12 is slidably disposed inside the second guide groove 10. A support frame 13 is connected to one side of the cutting blade holder 12. A rotary cylinder 14 is connected to the top of the support frame 13. The output end of the rotary cylinder 14 passes through the cutting blade holder 12 and is connected to a vertical threaded rod 15. A receiving block 16 is threaded on the surface of the vertical threaded rod 15. A second motor 17 is connected to the notch of the receiving block 16. The output end of the second motor 17 passes through the receiving block 16 and is connected to a main cutting blade 18. A positioning mechanism 19 is connected to one side of the cutting blade holder 12.

[0020] The positioning mechanism 19 includes a connecting block 191 connected to one side of the cutting blade holder 12. The connecting block 191 has a cavity 192 inside, and a buffer spring 193 is connected inside the cavity 192. A slider 194 is connected to one end of the buffer spring 193 and slides inside the cavity 192. A pressure plate 195 is connected to the bottom end of the slider 194.

[0026] Working principle: Motor 23 drives the lower feeding roller 24 to rotate. Since the lower feeding roller 24 and the upper feeding roller 25 are in contact, the upper feeding roller 25 rotates under the action of friction, together conveying the carpet forward. As the carpet is conveyed, the operator pulls one end of the carpet, and the moving block 5 moves, driving the first motor 6 and the side cutting blade 7 to move. After reaching the predetermined position, the first motor 6 starts, driving the side cutting blade 7 to rotate at high speed to cut the side of the carpet. Then, the electric push rod 11 starts, the output end extends, and pushes the cutting blade holder 1. 2. Slide within the second guide groove 10 to adjust the longitudinal position of the cutting blade holder 12. Simultaneously, the cutting blade holder 12 drives the positioning mechanism 19, which in turn drives the pressure plate 195 to press down, fixing the carpet in the designated position to ensure that the carpet will not move during the cutting process and to guarantee cutting accuracy. The rotary cylinder 14 is started, and the output end drives the vertical threaded rod 15 to rotate. The receiving block 16 moves, driving the second motor 17 and the main cutting blade 18 to move. The second motor 17 is started, driving the main cutting blade 18 to rotate at high speed to cut the top edge of the carpet.
